Is this normal? (read details) [possibly NSFW]?

Okay, I’m asking this question because I think I’m going crazy. It’s been such a long time since I last had sex with someone, many many months.
I can’t stop thinking about it. No matter what I’m doing, even if I’m watching a documentary about the North Pole. I can’t stand this, I walk on the street thinking “Okay, what would this one be like? Or that one?” But the thing is, I’m so definitely not the kind of person who will like just any guy. I blame Tom Hiddleston for that.
I don’t know anyone sexy enough, so I go out quite often but still I don’t seem to find what I want. They’re either too young, too old, too creepy (said by a girl who finds the Joker sexy as hell), too shy, too sleazy. Am I too picky?
I just don’t want to end up with someone I don’t really want.
Have you been there or in a similar situation? Am I going to lose my mind?

Also: what’s the longest time you’ve gone without sex?
